A wireless audio conferencing system has one base station and a number of portable parts each of which is able to establish a communication link with the base station. The base station is controlled to initiate and to terminate communication sessions with other communication devices over a communications network such as a LAN or a WAN, and the base station includes a DSP the implements a digital radio and system application functionality that monitors and stores certain operational state characteristics associated with the portable parts. The base station uses the stored operational state characteristics associated with each portable part to determine whether, at the end of a communication session, a portable part is connected to a charging tray or not, and if not, the base station operates to transmit a warning message indicating that a portable part is not being charged. |
